ADJUSTABLE BEnsE-HoLEEE.

have invented certain new and useful Im- 'provements in an AdjustableBrush-Holder, of which the following is a specification.

My invention relates to lmprovements 1n :brush holders and has for itsprimary object to produce a device of this character, that is adjustablelongitudinally and laterally, for use in connection with brushes ofvarious sizes. I

A further object of the invention hes in the provision of an adjustablehandle, whereby the holder when attached to the brush may be manipulatedin an easy and convenient manner. 7 7

A further object of the invention aims to provide a combined brushholder, tack puller, and scraper, said elements assistingin performingthe function of the scrub brush when used on floors containing stickysubstance.

Other objects and advantages of the invention will be apparent duringthe course i of the following description.

In the accompanying drawings forming a part of this specification andinwhich l ke numerals are employed to designate like parts throughoutthe same,

Figure 1, is a side elevatlon showing my improved holder attached to abrushof the ordinary structure;

Fig. 2, is a fragmentary top or plan vlew showing the adjustableconnection between the sections of the holder;

Fig. 3, is a bottom view showing the transversely adjustable clampsearned by the sections, and

Fig. 4, is-a detail sectional view showing the pivotal connectionbetween the sectlons.

In the drawings, wherein for the purpose of illustration I have shown apreferred embodiment of my invention, the letter A designates the holdercomprising sections 5 and 6 that are so shaped when joined together asto be of approximately the same configuration as the back of the brush Bto which they are attached. The section 6 has an extension 7 thatoverlaps the extension 8 of the section 5, as clearly shown in Fig. 1.Adja cent the free extremity of the extenslon 8 1 provide a verticallyextending pin 9 that ex tends upwardly through the longitudinallyextending slot 10 formed in the extenslon 7.

Specification of Letters Patent.

Patented May 16,1921.

Application filed November 6, 1919. Serial No, 336,190.

The portion of the pin passing through the slot 10 is equipped with thecollar 11 that is held thereon by the washer 12. The longitudinal edgesof the slot 10 are beveled so that the washer will lie flush with thetop of the extension. Thispermits the sections to be adjustedlongitudinally with relation to each other, for use in connection withbrushes of various lengths.

Extending transversely across the bottom of the sections approximatelymidway their length are grooves 13 adapted for the reception of theclamping plates 14. Each groove is provided with two plates, the innerends of which overlap and are slotted asat 15, a substantial distance toreceive the vertically extending bolts 16 that extend up through thesections being adjusted by the wing nuts .17. at their ends. Thus theplates may be adjusted laterally through the medium of the connectingbolts 16. At each endof the groove 13 a thin strip of metal extendsacross the grooves and plates being embedded in the sections, so as tolie flat therewith. The outer or free extremities of the plates 14': arebent downwardly at right angles and then inwardly forming hooks 19 thatextend down over the sides of the brush back and beneath the same, thusfirmly and securely holding the brush in engagement with the armsagainst any possibility of independent movement or casual disconnection.A fiber strap 20 extends between the bolts 16 of the two sections beingsecured thereon by the wing nuts 17 This strap constitutes a handle forsimplifying the manipulation of the brush and one of its ends isprovided with a series of openings 21, permitting the strap to beadjusted according to the length of the brush in connection with whichthe holder is used.

The forward end of the section 5 is recessed on its bottom forming apocket 22 in which a blade or scraping element 23 is pivotally mounted.This pivot 24 extends through the section adjacent its forward end andis adjusted by a wing nut 25. As clearly shown in Fig. 3, the scrapingelement when not in use is disposed within the pocket, so as not tointerfere with the operation of the brush. To move this memher to anoperative position the wing nut 25 is loosened and the plate willautomatically swing to its proper position, whereupon the nut 25 isagain tightened and the device is ready for use. The outer edge ofbrush.

sired.

In operation, the'sections of the holder are adjusted longitudinallyaccording to the length of the brushwith which it is to be used. Thewing nuts 17 are then loosened so as to permit lateral movement of theplates 14 which are adjusted according to the width of the brush back.l/Vhen the necessary adjustments have been made the holder is placedupon the back of the brush and the clamping plates moved inwardly untilthe clamping arms 19 firmly engage the edge of the brush, whereupon thewing nuts are tightened to the extent that the holder will be securelyattached to the The brush is then used in the ordinary manner and shouldthe floor upon which the brush is being used contain sticky substance,the scraping element 23 may be used for removing the same, thisfacilitating the performing of the function of the brush. If necessarythe strap 20 which constitutes a handle maybe adjusted according to thedistance at which the sections are placed. It is obvious from theforegoing facts that a device has been constructed which is simple andyet eflicient in operation.

It is to be understood that the form of my invention herewith shown anddescrlbed is to be taken as a preferred example of the same, and thatcertain changes in the shape,

size and arrangement of parts may be resorted to without departing fromthe spirit of the invention or the scope of the subjoined claims.

Having thus fully described my invention, I claim l. The combination ofa brush holder comprising two sections adjustably joined together,clamps extending transversely of the sections,-set screws for adjustingthe clamps, and a strap extending between the set screws of the sectionsforming a handle.

2. A brush holder comprising a pair of sections, overlapping extensionsextending from the sections, means adjustably connecting the extensions,transversely extending grooves being formed in the sections, andadjustable clamps secured in the grooves for clamping the brush.

In testimony whereof I have aflixed my signature in the presence of twowitnesses.
